A5 Disk Drive Description

The A5 Disk Drive is a solid state (FLASH) drive. There may be different drive
capacities being used, and due to continual changes being made by the drive
manufacturers these will continue to change from time to time.
Failures of this disk drive can be either hardware or software related. The first
step in troubleshooting is to determine if the failure is software related. If
software is found not to be the issue, the disk drive should be replaced.
Before replacing the A5 disk drive it is highly recommended that the factory
calibration data be backed up to an external drive if at all possible. If this data is
not backed up prior to replacing the disk drive all instrument adjustments and
performance verification tests will need to be run after the drive is replaced.
